530 • The line A pressure (P5) is less than 75% of the
setpoint for 200 milliseconds for any process.
• P5 is less than 75% of the P21 sensor reading for
4 seconds for a mixed-fuel gas process.
• P5 is less than 75% of the P7 setpoint for 4
seconds for an F5 process.
531 For a minimum of 200 milliseconds, the line B pres-
sure is less than 75% of setpoint.
533 For a minimum of 200 milliseconds, the F5 pressure
sensor (P7) is less than 75% of setpoint.

Corrective action
1. Look at the diagnostic code history for pressure-related codes.
The code history can help to identify where to look for flow or pressure problems.
2. Make sure that the inlet gas pressure for line A (P2) or line B (P1) is in the correct range.
3. If the measurement is too high or too low, use the regulators to adjust the pressure for the line A, line
B, or F5 gas to the correct range.
4. Examine the consumables:
a. Make sure that the correct consumables are installed.
b. Make sure that there is no damage or excess wear.
5. Replace the incorrect consumables or the consumables that have damage or excess wear.
Verification
Use the gas volume monitors that are near the pressure transducers to look for gas leaks.
Troubleshooting for low shield water pressure
Diagnostic code 532
Diagnostic code 532 identifies when the shield water pressure supplied to the cutting system is less than
the required range. This condition can cause system shutdown or poor cut quality. Examination of water
hoses, fittings, regulators, and possibly the use of a booster water pump can be necessary.
